This invention relates to locks, and has for one of its objects the productiony of a lock particularly adapted to automobile doors' and the like, and the provision of means for rendering the handle of the lock inaccessible to inadvertent violent action or unauthorized attempts to twist oit the handle from the lock.

A further object of thisinvention is the prod ation oi a simple and efficient means for moving the operating handle of a lock to and from anv operating position for controlling the operation of the lock. Y

yOther objects and advantages ofthis invention will appear throughout the following specif u cation and claims.

40 By referring to the'drawings,I it Will be seen that III designates a section through anfautomobile door and the like, which carries a door handle It. The normal operating position of the handle II isfspaced Afrom the outer 45' Wall I2 oi the door I0, but when the handle II is in a locked position, it is adapted to be pushed into and become seated within the recess or socket I3 formed in theouter wall I2; as shown.

ture I5 formed in the outer wall I2. A reduced shank I5, square in cross-section, lextends inwardly of the door I and is carried by they shank M. This reduced shank I6 extends through the squared aperture of the usual type lock having spring mechanism for returning parts to their normal position.

A collar 24 is locked upon the inner end of the reduced shank I6 by means of a locking screw 25; and this screw'extends through and works l0. in a spiral or cam slot 26 formed in the sleeve 21, within which sleeve 21 the collar 24 is mounted. The sleeve 2'! has one end thereof journaled in the socket 28 formed in the inner facev of the kinner wall 29 of the door I0, and the opposite end 15 journaled under the securing ring 30 carried by and secured to the lock I8. A gear 3I is formed on the sleeve 21 and meshes with a gear 32 carried by the shaft 33 of the inside handle t. The shaft 33 extends through the inner wall ,20' 2Q, asshown in Figure 5, and the gearr 32 is engaged by an over-center spring serving to yieldably resist rotation of the gear past center from either -side and thus prevent accidental swinging of the handle 3d from one position to 25 another.. The spring 35 is anchored at one end to the lock I8, as shown at 36. 'Ihe handle l! may be moved into and outof the recess I3 by swinging the handle 34 in a` selected direction f and rotating the gear 32. This will.' in turn ro.- tuY tate the gear 3I'and sleeve 2l causing 'the pin or screw 25 to travel in the slot 26 andy move the shank It in the selected direction for drawing the handle II into or moving the handle il out of the recess I3. When the handle II is within 35 the recess I3, 4as shown in Figure 2, the latch bolt Il may not be operated, but when the handle il is in the position shown in Figure 5 the latch bolt of the lockmay be operated in the conven.-

tional manner, the coil spring 14a normally urg- 40 ing the handle' II to a position out of the recess I3. The screw 25 carries a roller 25a which Works within the slot 24 and the inner end of the slot 24 is turned abruptly to provide an abutment shoulder 2.6@ to resist the movement vof the screw 25 longitudinallyl of the slot when placed in the position shown in lFigure 2 and slightly anchor thelocking screw 2.5, thereby preventing the returnof the parts to an unlocked position since thev roller 25a-.must pass over y,the abutment shoulder 50 251 in order to pass longitudinally of the slot'I 24. This: will tighten the locking device and tend to preventroad jars yfrom loosening theparts.

` The handle Il carries a barrel lockv 31' Within the. shank. I4 thereof and this barrel lock 31j l55 of the conventional type may be operated by a key 38 for moving the plunger 39 thereof inwardly or outwardly. A clutch rod 40 is slidably and rotatably mounted through the shank I6 and carries a square inner clutching head 4I which is adapted to t in the square aperture 42 formed in the end of the sleeve 21. A coil spring 43 is carried within the shank I4 and engages the head 43 at the opposite end of the clutch rod 40, as -shown inFigure 6, normally urgingthe square clutching head 4I out of engagement with the aperture 42. When the plunger 39 is moved inwardly by the operation of the key 38, the plunger 39 interts with the head 43 and the clutch rod 49 may be rotated thereby rotating the sleeve 21 in a selected direction to dispose the screw in locking engagement with the shoulder 26a and lock the handle in the recess I3 or move the screw out of engagement with the shoulder and permit the handle I I to move out of the recess I3 to the position shown in Figure 5. When the key 38 is removed the plunger 39 will recede within the barrel lock 31 and the clutching head 4I will be drawn into contact with the end of the shank I6. The rod 40 carries a radiating pin 44 for fitting in the notch 45 formed in the end of the shank I6 to hold the clutching head 4I in position and the rod 40 against rotation in the shank I6 when the key 38 is removed.

When a person within the automobile desires to move the handle II to an extended position, such as is shown in Figure 5, from the position shown in Figure 2, that is to say to move the handle IIv out of the recess I3, the handle 34 is swung so as to rotate the gear 32 in a manner to rotate the gear 3l in a clock-wise direction and cause the screw 25 to travel in the slot 24 or in a direction toward the handle II. After the screw 25 has moved out of engagement with the shoulder 26CL it may move through slot 26 and spring Illa will assist in forcing the handle II to an extended position.

When it is desired to unlock the handle II from outside the automobile and allow the handle to move to the extended position, shown in Figure 5, from the retracted position shown in Figure 2, the key 38 is inserted in the barrel lock 31 causing the lock to have clutching engagement with the clutch rod 49 moving the clutch rod 4G longitudinally within the shank I and causing the clutching head 4I to fit within the square aperture 42 in the sleeve 21. Then by rotating the key 33, the rod 40 will be rotated, thereby imparting rotation to the sleeve 21 and this will cause the screw 25 to travel within the spiral slot 24 out of engagement with the shoulder 2611. As soon as the screw moves out of engagement with the shoulder the spring I 4a may slide the shank I6 outwardly and move the handle II out of the recess i3. During this movement of the shank the sleeve 21 will be turned until the screw is at the outer end of th'e slot 26.

When the handle II is to be locked and thus prevent unauthorized opening of the door, pressure is applied to the handle to shift the shank I6 inwardly and seat the handle in the recess I3. During inward movement of the shank the screw 25 travels through the slot 26 and turns the sleeve 21 until the screw reaches a point close to the inner end of the slot. The key is then fitted into the lock barrel 31 and pressure is applied to shift the rod '40 inwardly and seat its head 4Iin the opening 42. The rod will then be turned torotate sleeve 2.1 and seat the screw back of shoulder 28. 'I'he shank I 6 will then be securely held against outward movement and the handle retained in the recess I3.
